What kind of gas should one use in a 2002 Artic Cat Snowmobile?

Question

The reason im asking is cuz the manual says to use only 87 octane, but i blew a piston and trashed the jug on the recoil side of the motor last winter. The mechanic says that is cuz i was using the 87 octane. he says i should be using the 92 octane premium.

Answer 1

most of the "sled freaks" up here in Alberta use premium , but you must avoid fuels with alcohol like the plague, it is a very "dry" fuel and it eats up 2 stroke motors have fun, stay warm, sled sober.

Answer 2

using sub grade fuel usually only affects the valves,i recommend mid grade fuel,but the higher the octane the better it cleans the fuel system
